I would tell your inlaws that, while the Giants are a good team, they are without doubt THE luckiest team probably in league history.
In our first SB meeting, obviously the helmut catch, the missed holding on that play, Assante's dropped pick, you can pick from a half dozen ridiculously lucky plays in the last few minutes that ALL had to go the Giants way for them to win. Oh, and Brady's injured ankle from the SD game, which I think had a huge impact on the SB.
Then in the 2nd SB matchup: first, they didn't even belong there, SF did. Then they lose decisively if Gronk is anywhere near 100%. Then Brady gets hurt midway thru the game. Then the very fortunate completion to Manningham (which I admit was more skill than luck, but a lot of luck too). Then the Welker drop while completely uncovered, the very close Hail Mary at the end, and I know I'm forgetting another 3 or 4 other plays late in that game too.
They are way beyond "making your own luck", which is why they'll never make it again, the odds are too great.
